Spark is a new collection of daily puzzles centered on a theme (Ants in Your Pants, You’re My Soda Pop) that is almost as playful as the games themselves.

Quick take: Try to figure out the subtle connections among different words and concepts in Links. Put historical (and contemporary) events in order in Chrono. Test your knowledge in This or That, where you’ll match pairs of things that sound deceptively similar to the correct categories, like deciding which is the Rebellion and which is the Rock Hellion: the Weather Underground or the Velvet Underground?
